The Royal Bump Watch continues!

Kate Middleton, aka Catherine, Duchess of Cambridge, recently stepped out for another public event, following weeks of staying out of the limelight and recovering from a pregnancy-related illness.

Wearing a gorgeous pastel blue (one of her favorite colors!) Matthew Williamson dress coat with brass buttons, black tights and killer black dress boots, the 32-year-old glowed and showcased her growing baby bump as visited the Valero oil refinery in Pembroke, Wales with husband Prince William on Saturday.

William and Kate, who wed in April 2011, used to live in a cottage in Wales, the U.K. newspaper The Daily Mail reported.

At the oil refinery, they met with workers and apprentices and got to create their own gasoline blend, the outlet said, adding that Kate asked her husband, "Shall I do one and you can do the other one?"

The U.K. newspaper The Telegraph reported that the couple was told it would take 15 hours to create a blend, to which William joked, "We will do the night shift."

Hundreds of well wishers of all ages, waited outside for the couple in the blustery weather, cheering and waving Welsh flags, the outlet said. Kate and William greeted several of their fans, including members of community organizations.

"She is just normal really but ever so beautiful, even more beautiful than the pictures show," The Telegraph quoted Tracey Olin, a founding member of Pembrokeshire Action to Combat Hardship (PATCH), as saying about the duchess. "She put us totally at ease and it felt like we were talking to anyone, not the future Queen of England.

The two are expecting their second child. Kate's current pregnancy was announced on Sept. 8. It was also revealed at the time that she is suffering from hyperemesis gravidarum, which is marked by persistent nausea and vomiting. It is a common pregnancy complication and she had also battled its symptoms while pregnant with the couple's eldest child, son Prince George.

She has since made several public appearances, including one at the Action on Addiction Autumn Gala in late October, but did have to cancel others, including a scheduled official trip to Malta, while she was ill.

William, 32, wore a black and white suit and red tie at Saturday's visit. He and Kate both donned red paper poppies that day in honor of the United Kingdom's upcoming annual Remembrance Day, which takes place on Sunday.
